Question 6

In this equation, aluminum-28 (\(^{28}_{13} \mathrm{Al}\)) is transforming into silicon-28 (\(^{28}_{14} \mathrm{Si}\)).
Step 2: Determine the Type of Radiation
To identify the type of radiation, we need to consider the changes in atomic number and mass number:
The atomic number increases from 13 to 14, indicating the emission of a particle that increases the atomic number by 1.
The mass number remains the same (28), indicating no change in the total number of nucleons.
Step 3: Identify the Radiation Type
The increase in atomic number by 1 with no change in mass number suggests the emission of a positron (\(^{0}_{+1} e\)), which is a type of beta-plus decay. This process converts a proton into a neutron, increasing the atomic number by 1.
